Analysis of a Three-Phase Uncontrolled Full-Wave Rectifier Under Induction Motor Rotational Conditions: A Technical Investigation

Abstract

Induction motors are among the most commonly utilized motors in modern engineering applications due to their simple construction, cost-effectiveness, lightweight design, high efficiency, and ease of maintenance compared to DC motors. Despite these advantages, controlling the speed and torque of an induction motor presents significant challenges. With advancements in control system technologies, one approach involves using a single-phase inverter operating at a standard frequency of 50 Hz to regulate the speed of three-phase induction motors. In this study, a three-phase uncontrolled full-wave rectifier is analyzed to evaluate its performance under induction motor rotational conditions. The system utilizes a 220V transformer to supply the rectifier. Simulation and data acquisition are conducted using PSIM software to ensure precise modeling and analysis of the rectifier’s operational characteristics. The investigation explores the dynamic interplay between the rectifier and motor system, emphasizing the impact on voltage stability, harmonic distortion, and efficiency.
